Large Loop Designs

Loops of 2 wavelengths or larger are generally used horizontally as multiband antennas, as described in the Large Loop Theory page. Often they are cut as a full wavelength for 160m, 80m, or 40m, providing high angle radiation on the fundamental, and lower angle radiation at twice the frequency and higher bands. Irregular shapes and/or non-resonant lengths can work well also, and sometimes it is a matter of putting up as large of a loop as will fit the available space and using it with an antenna tuner.
